Technical Examples

Bridges decks or panels for bridge decks made of a metal-plastic-metal sandwich with the plastic bonded to the metal plates so as to transfer shear forces therebetween. The sandwich plates may be constructed with either a solid plastic core or a composite core consisting of plastic, metal plates or structural shapes and forms within or without a frame of girders. Sandwich plate bridge panels without peripheral metal frames are held together only by the adhesion of the plastic to the metal plates.
